When I park my car, I always ensure that I am parked in the middle of the lane as possible. Sometimes the parking lots are small and I can't do anything about it but I will re-adjust my parking to make sure that the cars surrounding me can get in/out with enough room because I don't want any damages to my car. Same applies to parallel parking.
Unfortunately being nice and considerate of others, doesn't mean other people are also. I have had a couple of incidents of minor hit/run incidents where the cars parked beside me hit my car as they reversed, or parallel parked resulting in minor dents, scratches, dings and none left any notes. There weren't any witnesses, proof or cameras nearby. And the accidents aren't big enough to deal with my insurance company because my deductible is $500.
Once in a while, when I see a vehicle I park next to that is not in the greatest condition or poorly parked, and, just following my gut I will snap a couple of photos and their license plate just in case. If all is well, I will just delete the photo. After all, photos are digital and can easily be deleted.
For instance, today while going grocery shopping, the vehicle beside us (the red car) is not parked straight in the lane. You cannot see from the picture but the front end, rear end had damages. The side of the car passenger had white paint scratched and since our vehicle is white, I also wanted to document that our car was not involved with their paint. By snapping a photo, it keeps me at ease.
If I came out of a store and found you taking pictures of my car for no apparent reason I might have a problem with that. You need to be careful people who will ding up the sides of your cars without leaving a note will also be the kind of people who more than likely will take your being cautious as an invasion of privacy and may threaten or hurt you.
I snap one or two quick photos and they're not obvious that I am taking a picture of the car anyway. Usually the photo will have my fiancé in them (like shown above) so I don't think it's concerning or upsetting.
It's just like if you were going to an amusement park, any tourist spot or just wanted to take a photo - there are people around or cars, no one gets permission - they just take pictures.
Then there are people who want their cars taken pictures of because they have a vintage car, exotic car, custom car.
The reason behind this tip is BECAUSE I have had previous hit and runs where people hit my car without leaving a note though I know what kind of car was parked beside me but, I didn't jot down their license plate or have any proof, so they're free! The areas I have parked at did not have any surveillance cameras and, they have signs posted that says not responsible for any damages.
This tip also applies to when selling on Craigslist or anywhere online. You can take a picture of their car license plate, encase something happens or scammed. It happens all the time and its important to be safe than sorry.
I'm sorry you don't like my tip. We live in an era where everyone uses their phones to snap just about anything even if we like it or not. I know at the gym, I go to and pay a membership even though signs display "no videotaping", people do it anyway. I just get out of the way so I'm not in the video.
As one quite fond of my (as yet unblemished) car, and also prone to fitness, I far prefer to park at the far end of the parking lot. Cars are typically sparse and the walking to and fro helps keep me in shape.
